GB/T 20183.2-2024 Equipment for crop protection—Spraying equipment—Part 2:Test methods to assess the horizontal transverse distribution for hydraulic sprayers

Scope

This document describes the test method for evaluating the horizontal distribution of spray volume levels. The method is based on measuring the volume of spray liquid, the flow rate of the spray nozzle, or the pressure at the nozzle. This document is applicable to the production and inspection of sprayers that spray liquid on a horizontal surface. Sprayers have different characteristics in terms of spray delivery and control, and all three test methods can be used, with the measurement results complementing each other. Some test methods are not suitable for all types of sprayers. The applicable test methods are described in the informative appendix. This document is not applicable to aerial sprayers.
